Ford Mustang Forum : “harmonic balancer”

harmonic balancer

two weeks ago I took my 1994 mustang gt out on the track. I drove around the track three times then heard a poof... After that my baby didn't run the same.  It was very  and shook .  Different people told me it was this and that.  After tune up, replace plugs wires and distributer cap, oil change and cleanned out the fuel injecters, new fuel filter..I had a machanic/racecar driver from the track look at it. He found the problem right away. It was the harmonic balancer. The rubber on it wore out and it bounced out of place. after replacing it with a new one ... my baby runs like new
